� � GEOGRAPHIC SETTING: Kilkenny soils have plane and convex slopes on gently sloping to steep end moraines of the Des Moines lobe of the Late Wisconsinan glaciation. Their slopes � range from 2 to 35 percent. They formed in a mantle of clayey glacial till or flow till and underlying loamy glacial till on moraines. Mean annual temperature ranges from 45 to 52 degrees F. Mean annual precipitation is about 25 to 32 inches. Frost-free days range from 145 to � 175. Elevation above sea level ranges from 800 to 1500 feet. GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gicnr��c, Lcr�lal, Lc�lcr, Lc � Sucur, Lura, !�1�va�l.<<, and Sl�icicl� series. The very poorly drained Glencoe and Lura soils are in the lower lying drainageways and depressions. The somewhat poorly drained Lerdal soils are on gently sloping to moderately steep areas. Shields soils are poorly drained, and are on slightly � elevated flats. Mazaska soils are poorly drained, and are on slightly elevated flats and swales above or within areas of Kilkenny soils. Also, the well drained Lester soils and the moderately well drained L,e Sueur soils are associated in a few areas. � DRAINAGE AND PERMEABILITY: Moderately well drained. Permeability is moderately slow. Runoff is medium to very high. A perched seasonal high water table occurs at depths of 2.5 � to 4.0 feet during the period April, May, and June in normal years. USE AND VEGETATION: Most of these soils are cropped to corn, grain, hay, and soybeans. � Some areas are used for pasture and some are forested. Native vegetation is mixed prairie and forest species. DISTRIBUTION AND EXTENT: South central Minnesota and north-central Iowa. The series � is of moderate extent. MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota ' SERIES ESTABLISHED: Waseca County, Minnesota, 1963. � REMARKS: Diagnostic horizons and features recognized in this pedon are: Ochric epipedon - the zone from the soil surface to a depth of 9 inches (Ap horizon); Argillic horizon - the zone from 9 to 53 inches (Btl, Bt2, Bt3 horizons); Oxyaquic subgroup based on saturation above a � depth of 40 inches; Vertic subgroup based on more than 6 cm of COLE in upper 40 inches. Water table studies and field observations have verified a perched condition in most years, particularly in periods of extended rainfall. � ADllI1'IONAL DATA: Soil Interpretation Record number MN0376. ' PALMS SERIES The Palms series consist of very deep, very poorly drained soils formed in herbaceous organic material 16 to 5 I � inches thick and the underlying loamy deposits in closed depressions on moraines, lake plains, till plains, outwash plains,and hillside seep areas,and on backswamps of flood plains. Permeability is moderately slow to moderately rapid in the organic material, and moderate or moderately slow in the loamy material. Slopc ranges from 0 to 6 percent. Mean annual precipitation is ahout 35 inches, and mean annual temperature is about 50 degrees F. ' i 1
